Lindsay Lohan 911 Call -- Hotel Emergency Classified As Life-Threatening

Exclusive

0620_lindsay_lohan_911_launchTMZ has obtained the 911 call placed moments before paramedics rushed to Lindsay Lohan's side last week at the Ritz-Carlton in Santa Monica -- after a hotel worker claimed the actress was unresponsive.

The caller -- a male nurse who works for the production company behind Lindsay's new movie -- called the situation a "Code 3" ... which is emergency worker lingo for "use lights and sirens."

Translation: the nurse thought it was a serious emergency.

TMZ broke the story ... Lindsay informed someone from the "Liz & Dick" production team she wasn't feeling well Friday morning -- and producers dispatched a doctor to the hotel. Before arriving, the doctor called the hotel and asked someone to check on Lindsay.

Someone from the hotel went to Lindsay's door, checked on her, and determined she was "unresponsive." So the hotel then called 911.

Paramedics eventually arrived and decided nothing was wrong. They left without transporting Lindsay to the hospital.
